Sorry, good point, here's the my.cnf we're using. Please note however
that although the configuration may not be optimal, we have been using
the same config for benchmarking on Linux also. No matter how broken
this my.cnf is we still shouldn't find MySQL running half the speed on
an "identical" setups only switching from Linux to FreeBSD.
